numpy.mod() in Python Last Updated : 10 Feb, 2019 Comments Improve Suggest changes Like Article Like Report numpy.mod() is another function for doing mathematical operations in numpy.It returns element-wise remainder of division between two array arr1 and arr2 i.e. arr1 % arr2 .It returns 0 when arr2 is 0 and both arr1 and arr2 are (arrays of) integers. Syntax : numpy.mod(arr1, arr2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj], ufunc 'remainder') Parameters : arr1 : [array_like] Dividend array. arr2 : [array_like] Divisor array. dtype : The type of the returned array. By default, the dtype of arr is used. out : [ndarray, optional] A location into which the result is stored. -> If provided, it must have a shape that the inputs broadcast to. -> If not provided or None, a freshly-allocated array is returned. where : [array_like, optional] Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs : Allows to pass keyword variable length of argument to a function. Used when we want to handle named argument in a function. Return : [ndarray] The element-wise remainder i.e arr1 % arr2 .

For negative numbers, if width is not given, a minus sign is added to the front. If width is given, the twoâs complement of the number is returned, with respect to that width. In a twoâs- 3 min read Modulo operator (%) in Python Modulo operator (%) in Python gives the remainder when one number is divided by another. Python allows both integers and floats as operands, unlike some other languages. It follows the Euclidean division rule, meaning the remainder always has the same sign as the divisor. It is used in finding even/ 4 min read numpy.remainder() in Python numpy.remainder() is another function for doing mathematical operations in numpy.It returns element-wise remainder of division between two array arr1 and arr2 i.e. arr1 % arr2 .It returns 0 when arr2 is 0 and both arr1 and arr2 are (arrays of) integers.
